N5265 Pin Function, Voltage, and Circuit Diagram

The N5265 is a key IC used in audio amplification and control circuits. Here’s a breakdown of its pin functions and reference voltages:

• Pin 1: 12V - Pre-stage power supply, providing stable voltage to the initial circuit stage.
• Pin 2: 5V - Audio signal input, receiving the main audio source for processing.
• Pin 3: 0V - Mute control terminal; when high-level voltage is applied, it mutes the output.
• Pin 4: 0.1V - Volume control voltage input, used to adjust the output volume level.
• Pin 5: 7V - Filter end, connected to the filtering circuit for signal smoothing.
• Pin 6: 7.4V - Negative feedback input, used to stabilize the amplifier output and reduce distortion.
• Pin 7: 0V - Ground, serving as the common reference point for all signals.
• Pin 8: 7.5V - Power amplifier output, delivering the amplified audio signal to the speakers or load.
• Pin 9: 15V - Power amplifier level power supply, providing the necessary voltage for the final amplification stage.

Understanding these pin functions is crucial for proper circuit design and troubleshooting. Whether you're working on an audio system, amplifier, or custom electronics project, the N5265 plays a vital role in ensuring clear and stable signal processing.
